Hello everybody,

on my Raspberry Pi 4, Model B 2 GB, is a 802.11b/g/n/ac wireless chip, but i can’t see it:

lspci -nnk

uname -a

Linux DietPi 5.4.72-v8+ #1356 SMP PREEMPT Thu Oct 22 13:58:52 BST 2020 aarch64 GNU/Linux

I searched a lot, but I could not solve the problem. What is missing? What do I have to install? I read about firmare-update. How is this going on? Please help!

Hi,

many thanks for your request. Did you tried to activate WiFi within dietpi-config?

  1. dietpi-config > 7 : Network Options: Adapters >
  2. Onboard WiFi : [On]
  3. WiFi : Not Found | [On]
  4. reboot
  5. WiFi status should be WiFi : Available | [On] | Disconnected now

Thank you! I couldn’t see the wood for the trees.
